There are plenty of secondary reasons for this distress, but it seems to me that the underlying cause is everywhere the same: human beings, the ultrasocial mammals, whose brains are wired to respond to other people, are being peeled apart. Economic and technological change play a major role, but so does ideology. Though our wellbeing is inextricably linked to the lives of others, everywhere we are told that we will prosper through competitive self-interest and extreme individualism.
